A study of validity of implications of proofs An Approach to Imam Khomeini's Viewpoint

Authors

Abstract

Study of validity of implications of proofs is among fundamental discussions in both Usul al-Fiqh and Fiqh. Authorized conjectural proofs (amarat) and practical principles can have indirect juristic implications as they have direct ones. Investigation of validity of such indirect implications and effects is entitled investigation of validity of implications of proofs. Some Usulis hold that implications of authorized conjectural proofs are valid since the divine law-maker has treated them as knowledge and certitude while those of practical principles are not authorized because they are not treated so by the divine law-maker. Some other have accepted that difference but have argued that what proves validity of authorized conjectural proofs is unconditional with regard to their implications while what proves that of practical principles is not so. Imam Khomeini, however, holds that implications of authorized conjectural proofs are not valid because of being treated by the divine law-maker as knowledge and certitude. Rather, it is the custom of the wise that differentiates between implications of authorized conjectural proofs and practical principles
